YXFB Explosion-proof Electrical Contact Pressure Gauge
About YXFB Explosion-proof Electrical Contact Pressure Gauge
Hollysys YXFB Explosion-proof Electrical Contact Pressure Gauges are specifically designed for use in hazardous locations characterized by explosive atmospheres. These gauges are suitable for measuring non-viscous, non-crystallizing, and slightly corrosive gases and liquids under conditions of pressure, vacuum, or similar environments. The internal contacts of the instrument feature electrical configurations that comply with corresponding explosion-proof ratings. They effectively monitor medium pressure while providing essential functions such as automatic control, alarm activation, and signal transmission. Primary applications encompass a wide range of industries including petroleum, chemicals, metallurgy, power generation, food processing, pharmaceuticals, environmental protection, and machinery manufacturing.
